Hey Louis.
As far as I understand you got up until 15 October to complete the project (a little extension for us). Its really needed in my case.
I have just finished ass 3 now. Some of the questions are a real head banger! The project counts 40% towards our year mark. If you put alot of evert into ass 4, it will definitely help to push up the year mark (like in my case!)

Apparently there is some limitation in the myUnisa configuration that makes it impossible to set up a due date later than the 30th September, so the lecturer was forced to set up myUnisa like this.
But nevertheless the due date is the 15 October (today)
